Initially a little trouble but then super

After I installed TomTom Home, I was asked directly if I wanted to because have the latest map. I, of course, "yes" is selected. That turned out later as an error.
The map has been downloaded (over 1GB), installed afterwards. Shortly before the end (about 3 hours) there was an error.
I launched the TomTom -> no more map plan :-(

So I called the hotline to ... the lady was very nice and said I should just the TomTom format in Windows. Then I was able to install everything in the TomTom Home. I think I know why it gave the error.
Original software "TomTom applicaton for TomTom One IQ Routes Edition" version 8415 was installed.

This was also re-installed after formatting, only after the current version 9.026. Now I installed the current map, and lo and behold it worked. Something weird but maybe helps the tip one or the other:

I would only have to update the software, and then have to ask the "guarantee for the latest map version" (you can click on in TomTom Home under "Tools").

Now it was on the TomTom only the software + card, nothing else. Had to manually add the votes, because you can still see a lot of funny voices besides the two standard speakers add (for free). The standard voice clearest / clearest speaks. The rest I just for fun of it.
The voices you just can in Home, 2. Button - Select> 4. Button etc.

The nice lady at the TomTom hotline still wrote me Blitzer for all countries good, because I had asked her in conversation. Has it been worth something to anger :-)

The TomTom itself is of course very good, what more can I capitalize on this? Price / performance ratio simply.
